 <h1>WHY XSCHEM?</h1>
  <h2 style="text-align:left; margin-left:3%;">
   Have been a Cadence Virtuoso user for many years, in different companies.<br>
  </h2>
  <h3 style="text-align:left; margin-left:3%;margin-top:10px;">
   <ul>
    <li>Long startup time</li>
    <li>Creating new components way too complicated (you need a CDF, ask your CAD support and file a ticket).</li>
    <li>Memory Hog, keeps growing until all Virtual memory exhausted, then crash.</li>
    <li>One process handles all design windows. Process crashes, all work on all windows lost.</li>
    <li>Netlist extraction and many other functions are slow since all is implemented in skill language.</li>
    <li>Proprietary file format.</li>
   </ul>

  <h2 style="text-align:left; margin-left:3%;">
   Most Open source schematic editors are not for VLSI
  </h2>
  <h3 style="text-align:left; margin-left:3%;margin-top:10px;">
   <ul>
    <li> Gschem (or its fork, lepton-schematic) and Kicad's eeschema, can not handle complex VLSI designs.</li>
    <li> Xcircuit is one of the very few Open Source tools i found that is good for VLSI design.
         Has very accurate graphics rendering, allows arbitrary rotations, uses postscript as schematic save format.
         This makes scripted generation of schematic files a bit complex. Certainly one of the best tools
         from graphic quality standpoint.</li>
   </ul>
